Solution Overview

Problem

Existing housing elements for magnets and ferromagnetic plates are difficult to assemble due to magnets shifting during the assembly process, causing a slowdown in operations as they need to be repositioned before the plate is correctly constrained, leading to complex and time-consuming assembly procedures.

Innovation Solution

The housing element design includes seats for magnets with a central wall that prevents the ferromagnetic plate from moving during magnet insertion, and retaining members that hold the magnets by friction, allowing for easy and automatic insertion of magnets while keeping the plate in a predetermined position, simplifying the assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If magnets are inserted in the seats of the housing element and then the ferromagnetic plate is placed on top, then the housing element can be assembled, but the magnets may move from their seats and attach to the plate before correct positioning, causing assembly slowdown

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The ferromagnetic plate is pre-positioned in the housing element seat before the magnets are inserted. The plate includes positioning features that ensure correct alignment is established in advance, so when magnets are subsequently inserted, they are automatically guided to their correct positions without risk of displacement or attachment to the plate.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If additional constraint members (screws) are used to secure the ferromagnetic plate to the housing element, then the plate can be firmly constrained, but the assembly process becomes more complex and time-consuming

Engineering Contradiction:
Improveconstraint reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ferromagnetic plate is integrated directly with the housing element through pre-positioning and magnetic retention, eliminating the need for separate constraint members such as screws. The plate becomes an inherent part of the housing element assembly, reducing both structural complexity and assembly steps while maintaining firm constraint through magnetic forces.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If magnets are freely housed in the seat with only magnetic constraint to the plate, then the housing element structure is simplified, but the magnets may move from predetermined positions or come off the plate during assembly

Engineering Contradiction:
Improvehousing element structureVSAvoidmagnet positioning precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The ferromagnetic plate serves as an intermediary element between the housing element seat and the magnets. The plate includes positioning features that act as a mediator to guide and secure the magnets in their predetermined positions, preventing displacement or detachment while maintaining a simplified overall structure without requiring complex retention mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)
